Durablow Stainless Steel Crawl Space Foundation Fan Ventilator - Heavy Duty Ventilation System for Basement & Attic (Silver, Model M1) | Perfect for Home Moisture Control, Air Circulation & Mold Prevention

The condition of your crawl space has a major impact on comfort, home value and indoor air quality. It's easy to underestimate the impact your crawl space has on your home. After all, it's not a place that's visited on a regular basis. But the truth is that the condition of your crawl space really does have far-reaching effects that can cost you money while also compromising the value and safety of your home. Many of these issues have to do with crawl space ventilation. The traditional crawl space has openings or vents in crawl space walls that allow outside air to circulate below your living space. In the summer, moist air gathers at the crawl space and condenses on cooler crawl space surfaces. This steady dose of moisture causes to grow and wood to rot. Wet wood also attracts like termites and carpenter ants whose colonies cause additional wood damage. At all times of year, indoor air pollution can cause illnesses because of airborne spores that enter the living space through cracks and gaps in the crawl space floor. That's why we need a built-in de-humidistat crawl space foundation fan ventilator to turn on/off automatically when humidity raises. Main Benefits: 1. Reduces moisture in crawl spaces / foundation to protect home and occupants. 2. Increases air circulation to prevent condensation and wood rot. 3. Exhausts vent radon gas, treated wood gases and odors, prevents migrating into living areas.

The exact proportions of these and other trace elements depend on the specific uses planned for end product. Rust Resistant: An important characteristic of T304 that makes it suitable for damp place use is that it is corrosion-resistant. Chromium binds oxygen on the surface and protects the iron component from oxidation (rust). Long Lasting: The first use of T304 was in brewing and milk production but it was adopted rapidly throughout the food processing and building industry. T304 products will last several human lifetimes when properly maintained. Components: Stainless Steel T430 is a downgrade of T304, but it's still much better then galvanized zinc steel which will begin to rust if any surface damages and cut edges. Calculate Your Crawl Space. For crawl space, we suggest 6 ACHs (Room Size x 6). Durablow dual fans models have 220 CFM (cubic feet per minute). ACH (ac/h) : Air changes per hour, or air change rate, is a measure of the air volume added or removed from a space (normally a room or house) divided by the volume of the space. Room Size : Room Inner Space (Length x Width x Height) For more information, please see larger images in listing. Low Noise dB Level. For example of dual fans models, the noise level is 50-61 dB . EVA shock absorption pads are also included for installation to minimize the noise. People will NOT noticed the ventilation operation in house if installing properly.
